Broadcom Drivers don't work in Ubuntu 12.10? Try This

This is how I got my BCM4312 Wireless card working in Ubuntu 12.10 after the additional drivers didn't work.

Please Note: this is the STA driver, not the legacy b43 driver. 

1) Code: sudo apt-get install linux-source

And:

Code: sudo apt-get install linux-headers-generic

2) Then:

sudo apt-get install bcmwl-kernel-source

3) And then restart with :

Code:  sudo shutdown -r now

4) Reboot and it should have everything working! Please report if this method doesn't work for you.
